I've heard $5,000.00 for a rebuild every ten races on a 410. 360 start the year off fresh and then one time after that. I'd like to see some prices. I would think a top of the line 410 is about $10,000.00 more than a 360 at least. Then you have the rebuilds.

Aside from a catastrophic failure I would really think that to freshen a 410 would in all honesty cost you about the same as if you were to refreshen a 360/358. Being there is a limited amount of titanium in both motors most of your costs in a refresh would be common to both motors. While I have never done a refresh on a sprint car motor I can say I've done it on my little LSx motor and these are the items I'm sure they would also check on a 410/358/360

1. Pull the rods/crank, magnaflux and check for tolerances. If within tolerance - refinish. Any cracks or wear beyond tolerance - replace2. Clean and check block/cylinder bores against pistons. If bore is out of spec then rehone if material/rules allow. If pistons are out of spec for bore/out of round then replace pistons. Rings will always be replaced 3. In my little truck motor we just replace the pump everytime being it's a wet sump setup and they are cheap enough ($250). I'm sure these motors they don't replace everytime due to costs, but I'm sure they disassemble, clean, rebuild, and flow test the pump. If it doesn't meet spec it is replaced.4. Never dealt with methanol, but I'm sure they do the same here as the oil pump.5. Inspect oil tank and oil lines. Replace as needed.6. Once piston sizes have been determined the pistons, rings, rods, and crank will all be balanced as an assembly.7. Go through the heads and redo valves, new valve springs, valve seals, and keepers. Inspect and replace retainers as needed 8. Inspect cam, cam bearings, and lifters for abnormal wear and replace all.9. Replace all head studs 10. Clean all components (for the fifth time) and reassemble all with new gaskets and seals.

If you break it into it's smaller pieces I really can't imagine where it would be that much different other than the frequency. So if this is what all they do when a motor is refreshed, Yeah I would say $5,000 is a rough ballpark figure knowing as much/little as I do. When looking for some additional info I found this on the Internet. I figured you would find this interesting. It basically covers a father/daughter race team out in California where he runs 410s and she runs 360s. And what all he has done during motor refreshes/rebuilds. Kinda interesting. http://www.circletrack.com/enginetech/ctrp_0903_sprint_car_engine_teardown/viewall.html

I doubt ASCS rules can't be enforced. The price of everything is going up, from toilet paper to sprint car engines. Not much R&D being done on toilet paper.

But you can bet your bottom dollar there is some engine builder out there right now working on something new to give his motors that little bit of an edge.

Its all ready being said if car counts don't go up significantly Selinsgrove might go back to 358's. I'm still waiting to hear where all these new 360 teams are going to come from. I have yet to talk to anyone who switched to a 360 this year just to go race there. My opinion the track doubled their purse for the exact same car count. Hope I'm wrong and it all works but I just don't see it happening.

Well at least the purse increase is a good thing. Charlie has always been very good with his payouts. Hopefully that will attract more cars but more money doesn't always bring more cars. That one has always remained a mystery to me.

If you replace 358s at Lincoln where do you expect to get cars from?with Hagerstown back to running them there's already 4 Saturday night tracks with super latemodels Winchester is struggling bad with car counts Hagerstown selinsgrove and port may get enough cars for a full feature but that's about it

Your also forgetting about Bedford and Cumberland isn't too far off either. Long story short the pickings are slim for super lates.

There are cars out there, and Lincoln is a high profile track too. The trick would be to give them the night off whenever the 3SF series is racing. That would make Lincoln an attractive option to those who would like to run the full 3SF series.

I think if Lincoln made the switch you might see some veteran LLM drivers move up to SLM, it wouldn't be much of a stretch for drivers like Knaub and Sagi. I think in the first season you would likely see 12-16 cars and it would only increase from there with a decent payout and some touring events scheduled as well. I think the fans would be more excited about SLM than 358s also, considering people got up and left after the 410 race last week even with the 358s and LLMs still to come. SLM and 410 are both the top level of their respective type of racing, this I think would make fans more interested.

You would also see occasional visits by drivers like Rick Eckert who lives in York. He seems to be a home town favorite as I see shirts of his walking around at WG and Lincoln quite often.

Lincoln should run410 Sprints, SLM's and rotate the third division between Street Stocks, Legends, Mini Sprints and 305 Sprints.

Thanks,Jeff.

Back when KARS 358's started a claim rule was tossed around, but most motors were being built out of junk yard blocks and heads. There was a rule originally that you couldn't even use a new frame, it had to be used. That just goes to show what the class was intended for and how it has gotten so out of hand. The new injections and head rules have ruined this class from what it was intended. Back in 2000 to 2006 we could still run a stock 350 machined block and a standard 2 7/16 injection and be competitive. Hard situation to reverse and fix now! I love the 358's just don't like what has happened to them and would not start again at the cost. You may as well run a used 410 you can buy 2 for what a top 358 cost.
